[ Upstream commit 587d8628fb ]
This patch prevents the thinkpad_acpi driver from warning about 2 event
codes returned for keyboard palm-detection. No behavioral changes,
other than suppressing the warning in the kernel log. The events are
still forwarded via acpi-netlink channels.
We could, optionally, decide to forward the event through a
input-switch on the tpacpi input device. However, so far no suitable
input-code exists, and no similar drivers report such events. Hence,
leave it an acpi event for now.
Note that the event-codes are named based on empirical studies. On the
ThinkPad X1 5th Gen the sensor can be found underneath the arrow key.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
